White leghorn identification

[Rebel8888]

I bought these chickens from a guy selling white leghorns but they just laid a brown egg. Also, they look terrible. The guy was not taking very good care of them but we’ll change that.
Here are pictures of the hens and roosters.

What are they?

I just see hens. The one with the red earlobes, second picture is probably laying the brown egg. Looks to be mixed. The rest look like leghorns.

Poor things. I'm glad you're giving them a better life!

All the ones with the white earlobes do look like Leghorns. The one that may or may not be a rooster has red earlobes. I can't tell if its a male or not because the feathers are so damaged and I'm not able to see any male specific feathering but it's possible it's actually a hen that lays brown like @oldhenlikesdogs said.

All look like adult females to me. Just very battered and unhealthy ones, poor babes.
Only some are leghorns, at least one is some other white breed. She likely laid the brown egg.
Do they have a proper coop?
